java 傳json 設置 ES max_result_window

ES分頁查詢，想偷懶，數據超過一萬多一些可以設置一下max_result_window

 

Map<String,String> params = Collections.singleMap("pretty","true");
String json = "{"
+"\"index\":{"
+"\"max_result_window\":30000"
+"}"
+"}" HttpEmpty entity = new NStringEntity(json,ContentType.APPLICATION_JSON); response = restClient.performRequest("PUT","/_index/_settings",params,entity);

 

但還是建議使用scrollId 查詢。
